At long, long, long last, the boot screen you have been waiting for!
Since you are rebooting so much, why not enjoy your restart with Firefox?
Your startup experience is now enhanced with the beautiful and soothing
Firefox logo as the indicator at the bottom sprays fiery yellow and reds
outward. Then you can resume browsing and rest assured that the sites you
view today with Firefox 2.0 will view the same (if not faster) on that
shiny new Mac you have been wanting to get for the last 10 years.

Download the boot screens here, and follow the instruction to install
them.
